Ucaa

Ucaa is a gargantuant horned owl who is much more intelligent than the common beast. They carry a chalice from which they pour they clouds from. It's said that in the days after the arising, the owl looked down upon the dry Isle of Zephyr and felt such heartache that it resisted it's nomadic nature and used it's chalice to bathed the isle in rain until the first flowers flossomed.
Ucaa is seen throughout the Central Domain but has been known to journey to the air, nature and celestial domain through their portals. It's unknown if Ucaa has journeyed to the Domain of the Infernals, but they have been seen flying towards the south pole on occassion.
